2.4.1,-ac9,-ac13: lockup after "now booting the kernel"

Hello,

when trying to boot kernel 2.4.1, 2.4.1-ac9 or 2.4.1-ac13,
I get lockups right after the message "now booting kernel".
Kernel 2.4.0-test10 ist booting ok on the machine.

Rik van Riel suspected on #kernelnewbies this might be a bug in
the CPU detection routine.

The system in question has an Intel 430HX chipset (Gigabyte 586HX2 board),
104 MB RAM und an AMD K6-III CPU, though the old BIOS detects is as an
ordinary K6.
Testing vanilla 2.4.1 with or withour MTRR support made no difference.

Snippets of .config, 2.4.0-test10 dmesg, and /proc/cpuinfo are included below.

Any ideas what might be wrong?

Thanks in advance,

Florian
